Dempsey gets knocked for using Twitter to spout about of Fort Monroe’s rich heritage or a TRADOC Senior Leaders Conference in Williamsburg, Va. Nowhere do we see Dempsey using hashtags and rarely does he use Twitter to interact with anyone directly or even solicit opinions. Dempsey could have used Twitter to provide a glimpse into the Army’s discussions of several topics near and dear to him: the Army profession, leader development and decentralization. But no there’s dialogue.

“All told, he asked for soldiers’ input a grand total of twice, and didn’t retweet a single reply. For TRADOC not to cash in on a transformative technological innovation is just too ironic,” Ackerman writes.

Let’s be realistic. Senior Army leaders are probably not going to get comfortable overnight with a medium that encourages candor and open dialogue with, well, the planet. But Twitter is way too powerful a platform just to be used for the occasional thank you message or vague back-slappy missive.
